GAS BURNER Filed May 13, 1927 Patented Apr. 2,1, 1931 UNITED STATESCHARLES I-I. SLAUTER, 0F COLUMBUS, OHIO GAS BURNER Application filed May13,

This invention relates to improvements in gas burners and has for itsprimary object the provision of a gas burner adapted to promote uniformand complete combustion S of the gaseous fuel utilized thereby, toproduce a burner characterized by its odorless operation and a burnerwherein provision is made for securing an intimate and thorough mixtureof the fuel with the oxygen of the air to permit of the production of ahighly eliicient flame of green, violet and blue appearance.

Another object of the invention resides in the provision of a burnerformed to comprise a V shaped frame which is secured to a gas conduithaving an orifice in the upper end thereof, the diverging arms of theframe being shaped to support in a horizontal plane, disposed axiallyabove the orilices in said conduit, a flat delector plate, against theunder surface of which the gas stream is directed under pressure,whereby the impingement of the gas stream upon the under surface of' theplate serves to break up the stream and to permit of the intimate commingling of the air therewith, enabling active combustion to take placecontiguous to the peripheral edge of the plate. A further object of theinvention resides in forml@ ing the supporting frame for the plate sothat said frame will not interfere with the combustion taking placearound the peripheral edge of the plate.

For a further understanding of the invention reference is to be had tothe following description and the accompanying drawing wherein:

Figure l is a vertical sectional view taken centrally through theimproved burner comprising the present invention,

Figure 2 is a perspective view of the deflecting plate and itssupporting frame,

Figure 3 is a vertical sectional view of a modified form of theinvention,

Figure 4 is a horizontal sectional view taken on the line 4 4 of Figure3.

Referring more particularly to the drawing the numeral l designates anupstanding pipe or conduit through which is led gas, either natural orartiiicial, under pressure.

1927. Serial No. 191,204.

The upper end of the pipe or conduit is substantially closed and isprovided axially with a threaded port for the reception of a removabletip 2 in which is provided a gas orifice 3, which may be of anyappropriate diameter dependingl upon the kind of gas employed and alsothe pressures utilized. One of the features of the invention resides inenabling the burner to operate with tips possessing orifices of varyingarea, the burner permitting of eiiicient combustion regardless of theartilicial diameter of the gas port which may be selected, although forbest economy and eiiciency tips of certain selected area are to bedesired.

.In this instance, the outer part of the pipe l, adjacent to its upperend, is threaded for the reception of spaced binding nuts l which areutilized to receive and hold the lower end of a substantially V shapedframe 5 in connection with the pipe. This frame comprises downwardlyextending converglng arms which are substantially triangular incross-section, the lower ends thereof terminating in a circular web 6which is provided with an opening for the accommodation of the pipe l,and 'through the medium of the nuts 4 the frame can be rigidly held inits operative position. The upper ends of the frame arms terminate inhorizontally and inwardly directed portions 7, which, in turn, terminatein downwardly and vertically directed legs S, the lower ends of saidlegs being in this instance integrally formed with a horizontallyarranged, circular detlecting plate 9, which is arranged in a horizontalplane disposed at an appropriate distance above the pipe l and in axialrelation with respect thereto.

By this arrangement it will be seen that the gas stream issuing in athin long attenuated stream under pressure and at reir tively highvelocity from the orifice 3 strikes upon the lower axial portion of theplate 9 and is violently agitated and moved in turbulent eddying wavestoward the outer peripheral edge of the deflecting plate. While in thisrelatively violent stage of agit-ation the gas is` actively commingledwith oxygen drawn freely from the atmosphere so that a combustiblemixture of highly efficient proportions is produced w ich permitscombustion to take place around the peripheral edge of the disk orplate. In fact, in the operation of the burner thlre are no visibleevidences of combustion in planes below the under sur` face of the diskor plate, combustion apparently not taking place until the gases havepassed the peripheral edge of the disk and are in course of ascension.The color of the flames of combustion is indicative of efficientoperation in that the flames take on a vari-colored appearance of blue,violet and green, being a pronou ced blue when the operation of theburner is initiated and then producing the light green shades after theburner has been in operation for a short time and the disk or plateheated, however, the heating of the disk is not essential in procuringeffective operation. The burner has the advantage of the usual Bunsentype of burner but has no tendency to flash out or to burn back in themixer if the gas pressures fluctuate, thereby lending itself admirablyfor use in heating devices wherein thermostatic controls are provided.Again, through the construction of the device it is not necessary to usescreens or the like for preventing the gas mixtures from burning at theproper points, inasmuch as fiuctuation of pressures and volumes in thegas stream w1ll not produce uniform combustion.

In the modified form of the invention disclosed in Figures 3 and al.,the upper end of the pipe l has connected thereto a disk l0, to which issecured a plurality of upstanding legs 1l which support a circular plate12 in spaced relation above the upper end of the pipe l. In connectingthe legs 11 near the central portion of the plate l?. the intense heatof the flame will not come into direct contact with the 1l and therebyprevent the same from burning ell', sagging or warping.

'hat is claimed is:

1. In a burner of the character described, a circular flat plate, a gaaconduit having a restricted gas flow orifice therein situated in spacedrelationship from said plate to direct a gas stream upon the axialportion of said plate, and a support for said plate connected to theupper surface thereof whereby the under surface and edge of said plateare left free and unobstructed to the gas stream flowing in alldirections toward said edge.

2. In a burner of the characler set forth, a circular plate, a gasconduit having a restricted gas flow orifice therein situated in spacedrelationship from said plate to direct the gas stream upon the axialportion of said plate, said plate being so supported as to leave theunder surface and edge thereof free and unobstructed to the gas flowingradially in all directions under said plate.

In testimony whereof I aflix my signature.
